Hydraulics of vertical slot fishways

Vertical slot fishways are meanwhile the commonly used type of technical fish pass used for basin structures, in Germany and elsewhere. Based on natural measurements and evaluations of model tests performed by several authors, existing uncertainties regarding the calculation of specific current parameters are discussed and a calculation method for the hydraulic assessment of vertical slot fish...

Post-print version of: Fuentes-Pérez, J.F.,Tuhtan, J.A ... Vertical slot fishways (VSFs) are hydraulic structures which allow fish to swim around obstacles in rivers. These structures are subject to variations in discharge of either hydrological or operational origin, which result in nonuniform water - depth profiles, i.e. differences in the water Comparison between 2D and 3D Hydraulic Modelling ... Fishways come in a range of forms including pool types (e.g. vertical slot), denil fishways, and rock ramp fishways. The vertical-slot fishway consists of rectangular channels with sloping or stepped floors that are divided into several pools (Alvarez-Vázquez, Martínez et al. 2007). The water flow Juan Francisco Fuentes-Pérez Juan Francisco Fuentes-Pérez, Jeffrey A. Tuhtan, Mario Eckert,Filipe Romão, Maria Teresa Ferreira, Maarja Kruusmaa, Paulo Branco In Journal of Hydraulic Engineering Vertical slot fishways are subject to variations in discharge of either hydrological or operational origin, which result in non-uniform water depth profiles.
